Hey, Q.

The Wicked Edge team is in the process of squaring it away. One more week and I should be set.

 

There is one more thing I need to figure out after getting my stones back, but that’ll be a few weeks out to test and verify. If my guess is accurate, I’ll create a step a step and post it for peer review here.

 

Sincerely,

Drew

Alright, I’m back.

I want to thank everyone who offered advice in this issue. It was a monumental cause-check session that took an unexpected amount of man hours for you all to walk me through this.

I’m betting that this’ll be handled by WE directly.

Don’t think for a moment that I don’t recognize and appreciate you all for offering help.

Marc, I’m going to use this opportunity to rework my writing style. The past 2 days frustration will not go wasted or unlearned from. I will also buy a freaking proper, large, metal square next time we travel to a big town. No excuse not to have the basic tools on hand and organized.

tc, if this gets worked out and I have 0.00 vertical stones, I’m going to master that .5° convexing.

Again, blessings to you all, and I’ll see you at the next mystery.

Oh man, our replies were overstepping each other. I missed a few. The 200 grit left the marker, and I haven’t checked for dishing, yet. There’s a good straight-edge on the property, I’ll have to track it down.

It feels like my eyes will start weeping blood like a WE stigmata if I pursue this further, today.

 

God bless you all, and I’ll get to replying proper after I go calm down.

I’m done, Marc. It’s many of the stones, 50-1k. Thank you for your effort. Good stuff.

 

I’m going to request another set of stones, or return the whole thing for a refund.

Man… Listen. Either I’m not getting a fairly simple concept, or you aren’t. I’m about to lose the last of my mind.

All I want is for the finer grit stones to contact the bevel the same at the created, ground degree as the courser.

All things being fixed and constant, including the tilt of the blade, bevel stone contact should be constant between grits as well. The only thing variable are the paddles.

Now, to get an even bevel on a tilting blade, I’ll hold on to your formula for when I run into that problem in the future. Thank you for that.

Here’s the last experiment I’m doing today to highlight the problem:

 

100 grit, ground fresh bevel flat, apex to back of bevel, bur raised on both sides. Clockwork, and all  is well. My reasoning suggests, strongly, that if the 100 grit can reach all parts of the bevel flat, regardless of how the knife is, then twisting the paddles from 100 to 200 on the rod, cubing to 15°, the 200 grit should mimic the contact of the 100s. It should be a carbon copy of the courser grit.

Fingers crossed I can post these pictures.

I’m just not convinced. Regardless of how the knife is positioned in the vice, if it’s locked in tight and ground fresh, with no movement in it, that angle of bevel should contact the stones the same, whatever grit I use.

Everything is consistent, that I can tell, besides the stones.

Are you saying that this system will only work putting consistently angled bevels on steel with a knife clamped at 0.00 vertical from base?

I did remove steel to apex, each grit. I don’t mind uneven bevels, as long as the entirety is mirror polished and able to shave neck hair.

 

Let’s say I did take the knife out, straighten it up 0.00, (I’m not sure what I can do for the left-placed LAA, that may just be the way it is), regrind at 100 grit to apex, then change to 200, then 400, etc. Are you betting that that would give me flat, 15° contact between these different stones and fix the problem?

[Drew]

… it won’t let me post the last orange bottom reading picture. It reads zero, on the money.

 

Marc, looking dead on the point of the knife, the spine is clamped slightly left of center. It’s sitting more on top of the left vise-pin.

I know that testing 50/80 variance is like testing a hand grenade for accuracy, but, starting from the lowest to highest:

Found a small 90°.

 

Base bottom, degree bar, and vise bottom as contact points. Zeroed cube on base and vertical flat of square. Set paddle to measure vertical. Right paddle first, then left. Bottom first, then top. 800 and 1k sides against square. Holding paddles against the square-flat with pressure on bottom.

It’s a poorly controlled experiment, but best I have at the moment.
